BS EN 16297-2:2012EN 16297-2:2012 (E) 6 Standalone circulators without pump housing shall be measured in pump housing identical to the pump housing in which they are intended to be used.

32、 6.2 Procedure 6.2.1 Load profile for calculation of average compensated power input, PLavgThe load profile for calculation of average compensated power input, PLavg, for standalone circulators is shown in Table 1.

34、) Select and set a control curve (control curve or non-controlled curve) which is as close as possible to the reference control curve and reaches point (Q100%, H100%) within the tolerance of H100%. c) Change the system curve to reach the part load operating points. 6.2.3 Calculation of average compe

If more than one control curve reaches the point (Q100%, H100%) within the tolerance of H100%, it is recommended to make the calculation on more than one curve and use the curve which gives the lowest PL,avg. 6.2.4 Calibration factor The cal
